Vladimir Putin has suffered a relapse in his health, it was reported.
The Mirror reported quoting Russian telegram channel General SVR which has earlier made claims that Vladimir Putin is suffering serious medical problems including cancer.
The 70-year-old Russian president will undergo a new treatment in early March.
“Over the weekend, Putin underwent another medical check-up. The recent treatment did not give the expected results and a new one, based on the results of the examination, has been scheduled and will start on March 5. This can and probably will seriously influence the president's plans and decisions in the coming days," the report said.
Putin's “deteriorating health condition” means an “inability to actively participate in various activities during the treatment” and he will be unable to “fully participate in the governance of the [military operation in Ukraine]," the report added.
It was claimed that a major speech by Putin this week to the Federal Assembly in Moscow “will be adjusted” to take account of the medical issues.
Putin allegedly suffers from “bouts of coughing, dizziness, sleep disturbances, abdominal pain [and] constant nausea” as well as “the manifestation of symptoms of Parkinson's disease and schizoaffective disorder”.
